Significantly faster tile generation, bug fixes, Python 3.10 bump

generate-tiles Script Update

Updated generate-tiles script generate tiles from PostgreSQL using tilelive-copy with tilelive-pgquery.
If run without MID_ZOOM environment variable, this script will generate all tiles from MIN_ZOOM to MAX_ZOOM (inclusive), just like it did before, but also doing the metadata update (see below).

If MID_ZOOM env var is set, generate-tiles will first generate all tiles from MIN_ZOOM to MID_ZOOM. Afterwards, mbtiles-tools impute finds the most duplicated small tiles at MID_ZOOM, and treats them as "empty" -- it copies empty tiles to the next MID_ZOOM+1 level as is, without regenerating them. impute also makes a list of all non-empty tiles, and generate-tiles script generates one zoom level for just that list. Once done, the same process is repeated for the next zoom level until MAX_ZOOM.

Lastly, generate-tiles runs mbtiles-tools meta-generate to update mbtiles metadata unless TILESET_FILE is not set.
